二维码作为一种新兴的条码,在网络中被越来越多的使用。通过从多种图片格式中筛选出能显示出同等信息的最小存储量的图片格式,即单色BMP位图格式,然后通过分析BMP文 件格式,提出一种支持在线生成的网络图片生成算法,结合通用二维码组件生成的数据,可以在线生成网络二维码图片-Two-dimensional code as a new bar code in the network are increasingly used. By screening　a variety of image formats can show the same amount of information stored in the smallest of image formats, namely bitmap monochrome BMP format, and then by analyzing the BMP file format, proposes a support line generated network image generation algorithm, combined dimensional code component to generate data that can be generated online network dimensional code image
